Re: Nachbau Patent Robert Norrby

Hello, In my previous post, I spoke of the "Grüneisen-Schumann" report, it is in fact the "Grüneisen-Schering" report. Regarding the description of the Stromerzeuger, this 1925 report, like Robert Norby's 1920 patent, and contrary to the Kloss and Schumann reports written in 1926, does not mention "...

Re: Nachbau Patent Robert Norrby

Hello, Let us compare the drawing found in the Grüneisen-Schumann report from the Physikalisch-Technischen Reichsanstalt of September 1, 1925, in the R43-I/1186 document Hans-Coler-1925.jpg described as follows: The apparatus is assembled from copper plates, coils of wire and electromagnets. Each of...

Re: Willy von Unruh

Hi Rudi, Yes, you are right. There are other duplicates and only one drawing depicting the Stromerzeuger (very different from the versions in the Norrby patent and the BIOS report)  in the R 43-I/1186 document: R_43_I_1186_0133.jpg But, do you not find it a bit strange that a duplication of pages oc...

Hello Ecki and Rudi, I looked for "Willy von Unruh"  here  and found another copy of R 43 I/1186 file (the size of the complete compressed downloaded file is 247 Mo) containing scanned images of the document of higher resolution. Below a sample from page 85 to 91 R 43-I_1186-p85-91.zip In this versi...

Dear Rudi, In the document of the Reich Chancellery labelled "Erfindung des Ingenieurs Willy von Unruh und des Hauptmanns Coler zur Erzeugung von Strom ("Coler'scher Apparat", Schwindel)" (see link ) by the Federal Archives and registered R 43-I/1186 that you had got from the German Archives, I noti...

Hello Ecki, I found DRGM patents registered for "Diaphor Gesellschaft für Elektromedizin" and "Elektros Gesellschaft für den Bau elektromedizinischer Apparate" companies in the "Patentblatt: Vierteljährliches Namensverzeichnis 1925" and "Patentblatt: Vierteljährliches Namensverzeichnis 1928" registe...

Re: Willy von Unruh

Hello Ecki, It may be surprising that Hermann Weber, who was a businessman, not an engineer like Willy Unruh, had been involved in the DRGM 634869. But I think it can be explained by the fact he had the same weight (2/5) than Willy Unruh in the capital of the Deutsche Elektro-Zentral Gesellschaft co...

Re: Willy von Unruh

Hello Ecki, In fact, the  DRP Angemeldet No. 5101 - VIII main patent regarding the Stromerzeuger as refered in the 1915 paper article belongs to the pending patents category whose number is temporary and may be different from the final DRP number (if the patent is granted). Looks like that this cate...

Re: Willy von Unruh

Hello Ecki, There seems to exist no link between Willy Unruh and Ludwig Stange that would prove that the latter would have worked with the former. Yet, as mentioned in the legend of the article you found, the Diaphor "R" X-rays device used a High-Voltage Tesla transformer and the Stromerzeuger in it...

Hello Ecki, As the link to the file related to the 21st class in the DPK classification in the web.archive.org website I had given in my previous post seems no longer work, I have added the corresponding attached file below I downloaded yesterday. The most relevant subclass in the document is "21g" ...

Re: Willy von Unruh

Hello Ecki, Among the DRGM you searched for, it is interesting to filter the results with respect to the class scheme (number in bold below) in the Deutsche Patentklassifikation (DPK) : DRGM 559525 III / 1913 ( 54 g)-1152    (Sold by Willy Unruh to Alfred Kohn when HAPIKO was founded on August 9, 19...

Hello Ecki and Rudi, I searched the Finnish, Dannish and Hungarian patent databases (see links below) but I found no patent related to the Stromerzeuger.

Re: Willy von Unruh

Hello Ecki, You can drag my link to the discussion thread. I reread the articles related to the Unruh trial in 1924 which mention a technician named Ludwig STANGE who would have worked with Willi v. UNRUH since 1911 and would be the actual inventor of the first stromerzeuger. Did you find historical...

Hello Ecki, I have found the following reference to a patent from Robert NORRBY seemingly regarding the power generator in an administrative document from Luxembourg (see  https://docplayer.org/77860117-Memorial-memorial-grossherzogtums-luxemburg-grand-duche-de -luxembourg-jos-bech-vendredi-17-mars-...
